To all whom it may concern:

Be it known that I, JOHN W. HAIR, a citiin the countyof San'Diego and State of California, have invented certain new and useful Improvements in Wedges for Tool-- Handles, of which the following is a specification.

My invention relates to an improvement in wedges for tool handles, the object being to provide means for holding the head or tool which fits or is received over the end of the handle. y

. My invention relates to certam other fea- 15 tures of construction and combination of arts, which will be more fully descrlbed ereinafter and pointed out in the claims.

In the accompanying drawings Figurel is a View in perspective; Fig. 2 is a longitudinal section view, and Fig. 3 is a view of the screw.

A represents the wedge made of heavy A metal having'a certain amount of flexibility,

and 1, 1 are the win s, which are made in one piece or in two pieces molded or otherwise fastened together at the bottom so that they form an integral part. The wedge is larger at the top and tapers to a point, as atj3, which is made sharp so as to be driven into the endof a handle. 7

The inner faces of the wings are provided with grooves 2, 2, which tapertoward the bottom of the wedge and aremade screw threaded to receive the screw 4, which conforms to the shape of the grooves 2,2. The outer faces of the wings are provided with transverse grooves 5 forming sharp blades or ribs 6, which are pressed against the wood and sink thereinas the screw is forced or screwed into the wedge. The head 7 of screw 4'is made flush. with the body, and is rovided with a recess or opening 8 therein or the reception of the screw-driver for forcing it or screwin it into the groove 2 of the wedge, whereby g the flexib lity of the wedge the wedge can e. expanded to the requlred amountto prevent the head of the tool from sli ping oif the handle, and by the blades or ri s 6,which grip into the wood of the handle, will prevent the wedge from slippmg even in the slightest degree.

It is evident that slight changes might 'be' The wedge can be made so that the wings made in the form and arrangement of the several parts herein descril .1 without departing from-the spiritand scope of my invention, and hence I do not wish to limit myself to the exact construction herein set forth; but:

Having fully described my invention, and what I desire tosecure by LettersPatent is:

1. As an article of manufacture, a combination wed e for tools, which comprises .a

member sp it edge-wise throughout the greater plortion of 1ts length and a tapering member aving a thread, said member adapted to enter between the "split portions of the first mentioned member and be turned there.-

in, whereby said ta erin member is fed endwise and has the e ect o s reading the parts of the split member latera' y and evenly a proximately throughout their entire lengt 2. As an article of manufacture, a combination wed e for tools, which comprises a member spit edge-wise throughout the greater portion of its length, said split por tions being transversely grooved or corrugated on their outer surfaces, tapering members having threads, said members adapted to en-, ter between the split portions of the first mentioned member and be turned therein, whereby said ta ering members are fed endwise and have t e efiect of spreadin the parts of the split member laterall an evenly approximately throughout. t eir entire lengt In testimon whereof, I afiix my signature in presence 0 two witnesses.
